AERIAL NAVIGATION.

Specification of Letters Patent.

Patented Apr. 4, 1911.

Application led December 8, 1908. Serial No. 466,563.

To all whom' it may concern:

Be it' known that I, JUSTIN KAY ToLns, a citizen of the United States of America, residing at Stockton, county 0f Stockton, State of California, have invented certain new and useful Improvements in Aerial Navigation; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make anduse the same.

This invention relates to improvements in aerial navigation, and more particularly to raising and sustaining means for flying machines. p

It consists substantially of a construction providing an aerogyroplane, which latter preferably has a plurality of blades rotatively associated therewith at the perimeter thereof.

' An object of the invention is to provide a device of this class having a large liftino and sustaining capacity, also one that will lift vertically and have considerable sustaining capacity in the event of the rotating means ceasin to act.

A further o Iject is to produce a gyroscopic effect, so thatthe apparatus shall not be liable to overturn through air currents and eddies.

It is also an object to provide a device of this description that will be light and strong in structure.

Further objects and advantages of the invention will be apparent upon consideration of the following specification, reference bein had to 'the accompanying drawing, in whic Figure '1 isl a plan view, portions of the apparatus being roken away; Fig. 2 is a central vertical section; Figs. 3 and 4 are sections onlines 3-"3 and 4 4 respectively h of Fig. L

5 run and having its advancing edge some- The central shaft 2 may be that to which the Propellers usually are attached in that class of flying machines designated as hellcopters, and may be adapted to be driven by any suitable motor- (notshown) 1n the direction indicated b the arrow. To shaft 2 a hub 3 may be a Xed and connected to rim 4 by spokes 5. A disk 6 of silk or other suitable material is secured at its p erlphery to the upper edge of rim 4. On rim 4 are secured a number of blades 7 each extending outwardly from lthe periphery of the yconstitutes an aerogyroplane;

orination of the disk 6 in use; and it also serves as a means to which the blades 7 can be attached and the spokes and braces secured.

While the rim 4 is preferably made to have a portion thereof depending, as shown, it will be evident that this feature may be dispensed with and the blades may then be attached to the rim at or near to the edge of the disk 6.

From the foregoing it will be understood by those skilled in the art that the structure comprising the rim 4 carrying the disk 6 and mechanically connected to the shaft 2, which is adapted to be used in practice with blades 7 arranged around the periphery thereof, or not, as may bel desired.

The mode of operation of this device' is as follows': Motion being communicated to shaft 2, the device as a whole rotates. Blades 7 draw the air from above the upper surface of disk 6 and throw it downwardly beneath said disk, thus raising and sustainin the device and the apparatus to which it 1s attached. The gyroscopic effect produced by the rotation of the diskv gives airships to which disks are attached great inherent` stability.

One form of structure embodying the 1nventionfhas been described, and illustrated, but it is obvious that other forms and I nodications may be made, and the right 1s re served to all such asrcome within the spirit and scope of the invention.

I Iclaim:

1. In raising and sustainmg means for aerial navigation, the combination of a rotating disk of silk or other sultable Inaterial and a rim therefor, with a plurallty of blades rigidly attached at the periphery of the rim and extending outwardly therefrom. l

2. In a raising and sustainin devlce for aerial navigation, a horizonta ly rotating disk, a downwardly depending rim thereon, and a plurality of blades attached to said 3. In raising and sustaining means for -arranged on' the periphery of the aerogyrosecured thereto,

aerial navigation, -the combinationl lwith an aerogyroplane comfprising a rimv and a disk same, and a plurality of blades arranged on the periphery ofvsaid aerogyroplane. 4. In sustaining means for aerial navigation an aerogyroplane comprising a substantially rigid' rim, a disk of silk or other suitable material' secured to saidy rim, a shaft,

and means for connecting said rim to said shaft.

5. The combination of anv aerogyroplane comprising a substantially rigid rim, a disk secured to said rim, a shaft, and means for connecting said rim to said shaft, with blades plane, substantially as described.

' 6. The combination of an aerogyroplane means for rotating then comprising a substantially rigid rim, a disk secured to said rim, a shaft, and means connecting said rim to said shaft, with blades arranged on the periphery of the aerogyroplane and extending outwardly therefrom,

the advancing edges thereof being somewhat.
